19 Claims.

This invention relates to apparatus for handling dough. Specifically, this apparatus is designed for the purpose of treating the dough and rolling the treated sheet into a spiral vform for 5 cinnamon rolls before they are placed in the oven for baking.

The apparatus is adapted to receive a large mass of dough and squeeze it between the shaping members which reduce its thickness and 1 gauge. its width, and then pass the flattened dough 'strip to a conveyor moving over the solid table where the flat strip is again treated with pressure members that further compress it and assist in sealing the gases within the flattened mass. At the end of the conveyor the dough strip is transferredby the pressure rollers to a lower conveyor where one margin surface of the dough strip receives a coating of water or the like while the remaining or major portion of the width of the strip is coated with a suitable oily substance. Sugar and cinnamon, or other flavoring is next sprinkled upon the oiled surface during the travel of the dough on the lower conveyor. After receiving this treatment the dough strip is operated 25 on by a spiraling cylinder disposed oblique to the line of travel of the conveyor which roller coils the strip in an oblique manner and allows it to pass beyond the end of the cylinder at one margin of the conveyor. When leaving this cylinder the 30 water coated margin of the coiled dough is outermost with its edge disposed helically around the rolled strip. It is desirable however to straighten out this outer edge of the dough so that it is par-,

allel to the length of the rolled piece. This is ac- 5 complished by operating on the rolled mass with the second cylinder that is oblique to the lineof travel of the dough and extends over the margin of the conveyor opposite the first named cylinder. This operation straightens the long mass of 40 dough so that the edge of the water-coated margin is disposed in a substantially straight line longitudinally of the mass. A suitable cutter wheel-next engages the dough and severs it into small pieces ready to be placed in the pans or trays in which the cinnamon rolls are baked.

\ The operation of this apparatus is entirely automatie and suitable controls are provided for.

discharging-the water and oil coating materials at the proper time, aswell as controlling the discharge of the sugar and flavoring after the coating has been performed. The operation of the apparatus is rapid and the rolls which leave the lower conveyor are all of the uniform size. During transit of the dough through the apparatus it is not e ry for the a te dant to andle the EEC '7 1943 v dough until the small pieces leave the discharge I paratus that is made of simple and sturdy parts that will not readily get out of order, and which is economical to manufacture so that it may be cheaply produced and sold to the user for areasonable retail price.

Further objects and advantages of the present. invention will be apparent to persons skilled in the art after the nature of the apparatus is understood from the following disclosure. The apparatus embodies the ,novel construction, combination, and arrangement of parts substantially as herein described and as illustrated in the accompanying drawings, and finally, as pointed in the claims.

The invention is herein shown in a particular or typical embodiment, but this is not to be taken in any manner as the limiting the scope of the claims thereto.

The drawings are more or less schematic, and. in the difierent views the same reference characters are used to identify like parts wherever they appear.

As illustrated in Fig. 1 this apparatus embodies an elongate supporting structure which comprises a flat table I0 preferably a metal sheet having down-turned longitudinal edges to which a plurality of supporting legs are attached to dispose the table at the desired working height from the floor. This table I0 is traversed from left to right by an endless conveyor II which passes around the drive pulley l2 at the left end of the table and around the free pulley l3 at the right end, and the return portion of the apron conveyor moves below the table. The pulley I! has a sprocket |4 secured to one end of its shaft. which sprocket is engaged by an endless chain l5 that is actuated by a drive sprocket l5. An

electric motor I1 is mounted on a shelf below the table and ,its shaft is suitably connected to a speed reducer l8, the slow shaft of which projects beyond the housing of the speed reducer and has the drive sprocket |8 secured to it. The chain l5 after leaving the sprocket |.4 moves upwardly to actuate other parts of the apparatus to be later described, and then back to sprocket I5.

Suitably supported above the table l0 there is a platform ii! that is preferably a metal sheet having up-turned longitudinal flanges 20 and an endless conveyor apron 2| traverses this platform in a direction from right to left. After leaving the left end of ,the platform the conveyor apron 2| passes around an idle pulley 22 that has its shaft journaled in side plates 23 extending above the table. Beyond the right end of the platform IS the apron passes around the driven pulley 24 that has its shaft journaled in uprights 25, and a sprocket 21 is secured to an end of the pulleyshaft and is driven by a chain 28. Below the right end of the table there is an electric motor 29 that is connected with a suitable speed reducer 30 and the latter has its slow shaft projected beyond its casing where it has a small sprocket 3| secured to it to drive the chain 32.

A suitable supporting frame 33' is connected at its ends to the uprights 26 and carries suitable journaling blocks for the shafts of upper and lower pressure rollers 34 and 35 respectively. The shaft of roller 35 projects beyond its bearings and at one end is provided with a gear 35 that meshes with a gear 31 on the adjacent extended end of the shaft of roller 34. The other end of the shaft of roller 35 is provided with a sprocket 38 with which the drive chain 32 engages. A similar sprocket 39 is secured to the other end of the shaft of roller 34, which sprocket 39 is engaged by the chain 28. Movement of the drive chain 32 rotates the lower roller 35 in the direction of the arrow and a gear 35 connected with its shaft actuates the upper gear 39, which in turn rotates'its roller 34 together with its sprocket 39, and it also drives the conveyor apron 2| through the medium of the chain 28 and sprocket 21 on the shaft of conveyor pulley 24.

A large sprocket 40 is secured to the speed reduceralongside the small sprocket 3| and a chain 4| engaged with said sprocket extends longi- -tudinally to themid-portion of the apparatus where it drives a'horizontal shaft 42 through the medium of a sprocket connected to said shaft. A-

second sprocket on this shaft 42 is engaged by a driven chain 43 that extends to and d ves it sprocket on a second horizontal shaft 44 to the left of the first named shaft 42. These elements are adapted to actuate certain portions of the apparatus which will later be described.

There is a chute 45 above the platform l9, which chuteis adapted to receive the dough batch and which is inclined downwardly-to feed the dough toward the pressure rollers 34 and 35 so that the dough is discharged from the chute into a space between these rollers where it is compressed into a flat strip. Marginal guide plates 46 are mounted for adjustment toward and from each other adjacent the discharge end of the chute 45 and are adapted to guide the dough and limit the width of the flattened strip passing between the pressure rollers 34 and 35. After leaving the rollers the strip of dough passes to the conveyor apron 2| by which it is conveyed from the right end to the left end of the apparatus. During its transit along the platform I! the dough strip passes successively under the series of rollers 41, 48, 43, 5,which are adapted to further compress the dough and condition it for a final compression which takes place at the left end of the apparatus. The return run of the conveyor apron 2| after leaving. the pulley 22 passes over a guide plate 5| which holds the conveyor taut and also raises the return run of the conveyor to a plane slightly below the platform |8 so that it will clear the mechanism which is mounted upon and operates on the table I. The rollers 41 to are of solidmetal in order to increase their weight and their trunnions are mounted in vertically disposed slots in the side flanges 20 of the platform l9 which permits the rollers to be freely raised or lowered with respect to the platform. The bottoms of the slots, when the dough is passing under the rollers, are below the trunnions so that the weight of each roller is exerted against the surface of the dough strip and assists in conditioning the dough while reducing the thickness of the strip. The width of the strip of dough passing into and between the pressure rollers 34 and 35 at right end of the apparatus is readily controlled by turning a small crank 52 on the end of a shaft 53 that has right and left threads on its end portions. This shaft is journaled on the chute 45 and the guide plates 41 have suitable bosses that are bored and tapped to be engaged by the threaded portions of the shaft '53.

The spaced frames 23 are provided with means for adjustably iournallng the trunnions or shafts of two pairs of pressure rollers 58 51 and 53-59 that are disposed so that the strip of dough leaving the conveyor apron 2| will be received between the upper pair of rollers 58-51 and be discharged therefrom in an oblique direction downwardly to the lower pair of pressure rollers 58-59. -By means of this set of rollers the dough is transferred from the upper conveyor apron 2| to the lower conveyor apron II in a continuous manner. The ends of thetrunnions or shafts of the upper pair of rollers 54-51 have gears 53:: and 51a respectively secured to them which gears are in mesh with each other so that these rollers rotate simultaneously in opposite directions rela-. tive to each other. Similarly, the shafts or trunnions of the lower pair of rollers 58-53 extend beyond their bearings and have gears 58a and 53a respectively secured to them, which gears are in mesh with each other so that said rollers are simultaneously actuated in the opposite directions. The end of the trunnion or shaft of roller 53, opposite the end thereof which carries t the gear 59a, has a sprocket 60 secured to it 5 vided with a sprocket 6| that is connected, by

means of a chain 62 with a sprocket 63 alongside the sprocket 60 whereby the rotative movement of the latter sprocket is transmitted to the upper 7 pair of rollers 56-61 and cause the latter rollers to be rotated in the same directions as the respectiverollers 68-69. I I The dough strip, after being transferred through the medium of the two pairs of rollers as above described, is disposed upon the adjacent portionof the conveyor apron II and begins its reverse movement from left to right. A short distance from the transfer rollers the dough is engaged by a pressure roller 64 which derives its motion from the chain 65 and sprockets that 0 are connected'to saidroller and to the roller 69. A suitable bridge-frame 66 is mounted upon the table and spans the apron II. The swinging trigger finger 61 is pivotally supported by the bridge frame in a pendant manner from a hanger 5 68 so that the lower end of this finger is directly in the path of the moving strip of dough which as shown in Fig. ljis approaching this trigger. When the -moving strip contacts the trigger 61 the latter'will swing to operate a mercury-switch 0 69 which is suitably connected by electric conductors to a pair of magnetic valves 'I0-II suspended below the table.

The above-mentioned valves control the flow or discharge of suitable fluids that are to be coated upon the strip of dough. The magnetic valve I0 controls the feed pipe I2 leading from a waiter receptacle I3, and the magnetic valve II controls the feed pipe I4 leading fromra receptacle I5 containing a suitable oily liquid. These receptacles or containers I3\and I5 are. air tight and a constant pressure is maintained thereinby means of a suitable air compressor I6 that is driven by a motor I1. The compressor is connected to the interiors of the receptacles by a .pipe I0, having T'-coupling I9 from which branch pipes 80 and BI lead into the respective containers. The discharge side of. valve I0 communicates with a pipe" leading up to a plane above \the apron where it extendsinwardly under the bridge frame and its discharge end 83 is so, located that the water" is permitted 'to drip upon one marginofi the dough passing under the same. The magnetic valve I I has a'discharge pipe leading upwardly to about' the. plane of-the water or 85 that is perforated through its lower segment to remaining surface of the dough strip to the edge opposite the margin which iswater 1 treated. 0

strip and distributes the liquids evenly across the respective proportionsof the face of the strip. After passing-the spreading roller 96, the leadadapted to operate amercury switch 00 and close, the circuit, to an'electrlc appliance 00 mounted 0 uponthe sidefgo'f the tali1e.."rhiselectric applionce, may be in the-form of a damper motor, a solenoid or;other automatic device. Its function is to operate the movable member or sleeye 90 of the toothed clutch that is connected with the 5 pipe 02 where it is provided with a discharge tube After receiving-these coatingsof ,oil and water, the dough strip passes beneath a spreading roller,

,86'that rests upon thetopsurface of the doughappliancell-by a rod or'shaft II. A spring 02 l exerts its tension to-shift the movable clutch member 90' out of. itscoacting member 99 when the switch is operated to open the circuit to the electric appliance 09. The clutch members 90 and 93 aresupported upon the outer end of a shaft 94 that is journaled in suitable bracket members 95 extending above the table a suitable distance. The shaft 94 has Q. sprocket 96 on its end nearest the clutch that is driven by a chain 91 deriving its movement from a sprocket/90 on the adjacent end of the shaft 44 above mentioned.

A suitable container 99 is mounted on the oily liquid and does not provide a coating upon the margin of the dough which has been coated with water.

After the dough has been treated and coated as herein before described, it is engaged by a suitable roller that operates upon it to coil the. dough in an oblique spiral with the water coated margin outermost and disposed in a helical manner upon the exterior of the coil of dough. The

elongated rolled mass is then straightened by engagement with another roller so that the helical outer edge of the watered margin is then .disposed longitudinally in a substantially straight line on the outside of the coil. I

In order to operate .on the flat strip to coil it spirally and then straighten the helical margin of' the roll, suitable novel-devices are provided between the container 99 and the discharge end of the conveyor II. A turret bracket IN is secured to the side of the table I0 near the loca-' tion of the clutch. This turret has a suitable upright standard and upon the top of the stand-'- ard there is a hollow embossment I02 to receive the spindle or trunnion of a corrugated roller I03. The trunnion of the roller is shouldered at the. embossment to guide it and said trunnion projects through the embossment where it has a sheave' I00 secured to it that is. driven by a belt I 05 deriving movement from a sheave I06 on the outer end-of the shaft which is journaled in the table 'leg or support immediately below the sheave I04. As seen in Fig. 3 and .in the diagrams-Figs. 6, 7, and 8 the aids of the corrugated roller 103 is oblique to theline of travel of the apron and-said; roller extends across the table close to the top surface'of the apron and termi-. nates at its free end in an acorneshaped end. I0'I near the-opposite side of the table. There-is an upright shieldv orfdeflecton 10% secured to the side of the table which is ;nearest the tapered end of the roller- II} to maintain the roll of dough on the;conveyor.-apro n. roller is driven in a direction opposing the direction of travel or the dough strip on the apron andit A, is thereby adapted torollthe dough strip obliquely' while the .latter is, moving along with the apron. This action ionnsa coiled elongate-mass which leaves the-roller at the tapered end approximately in contact with'theshield or.d"e-

'flector I00 along which the roll will travel-fav shortdistance longitudinally with the apron aw the closevto the margin thereof. This coiled mass of dough has the sugared and flavored portion innermost of the coil, while been coated with the water is the "outermost layer and this layer is disposed in a helical manner around the roll of dough.

It is desirable to straighten the above described helical layer so that it will be longitudinally disposed in an approximately straight line along the roll of dough before the roll is cut into the small pieces for baking. In order to'do this the rolled mass is warped by a second corrugated roller I09. This latter roller is disposed oblique to the line of travel or the apron and extends partly across the apron, width thereof from the side of the table upon which the shield or deflector N18 is mounted; -A turret bracket H0 is. secured to the table and is provided with an upright portion that terminates in a hollow embossment I II that is horizontally bored to receive the shouldered portion of the trunnion or spindle of the roller 109. The end of'the trunnion projects out of the embossnient HI and has a sheave H2 secured to it that is actuated by a belt H3 deriving its motion from.

a sheave on the end portion-of the horizontal shaft 42 that is .driven by the motor 28 at the discharge end of the'apparatus. The spirally rol ed dough with the helically disposed water coating layer outermost is engaged by this oblique roller I09 which rotates in a direction opposing the line of travel of the apron 'H and bodily warps or distorts the dough roll in a manner which straightens the helical outer layer sothat latter when the dough roll leaves the outer free end of the roller I09 at the center of the conveyor apron the coiled mass will be straight ened with the water coated margin outermost and extending in a substantially straight line.

dough passes under a dividing or cutting device which is in the form of a central body H5 of cylindrical shape that has a spindle I I6 projected beyond its ends and freely journaled in elongate vertical slots ll'lj'of upright side plates H8 se-' 'cured to the table. The cylindrical body H5 is provided with longitudinal disposed cutter bl'ades H 9 that project radially therefrom, and the ends of the body are provided with disk-shaped plates I20, the diameters of which are less than the periphery of the circle described on the cutting edges of the blades I I9. This structure is adapted. to be rotated by the engagement of the cutter blades H9 with the apron II and when the roll of dough is engaged by these bladesthe latter will cut the dough into the proper sizes for use in baking the cin'namonrolls.

In practice the small pieces of dough are removed at the discharge end of the apron ll, placed manually in suitable pans, and then deposited in the oven for baking. Throughout the Y entire operation of the apparatus it is not necessary for the attendant to handle the dough owing to the fact that all the steps performed by the apparatus are of an automatic character.
